What is a solar battery system?
Power stored for later use
A solar battery system stores electricity generated by solar panels so that energy can be used when it is needed most. Instead of using all solar power immediately during daylight hours, a battery system allows excess energy to be stored for nighttime use, grid outages, peak demand periods, or operational backup.
Integrated solar energy management
In a complete solar installation, the solar panels generate power, the inverter converts that power into usable electricity, and the battery system stores surplus energy for later use. In larger systems, a power conversion system, or PCS, manages the flow of electricity between batteries, solar generation, the grid and operational loads.
Built for Africa’s power challenges
Solar generation is strongest during the day, but energy demand often continues into the evening. Grid instability, load shedding, rising tariffs and energy access challenges also mean that users need more than solar production alone. They need dependable stored energy that can be dispatched when the grid is unavailable, expensive or unstable.
Modular systems for stable energy
A WEG Africa solar battery system is designed to support that need. Our battery systems are modular, safe, efficient and built to work within complete solar solutions. This gives homeowners, engineers, consultants, procurement teams, facilities managers and project owners a practical route to more stable, flexible and sustainable power.

How a solar battery system works
Capture excess solar power
A solar battery system works by storing surplus electricity generated by solar panels. During the day, solar panels produce DC electricity. The inverter converts this electricity into AC power for immediate use. When solar production exceeds current demand, the system can direct surplus energy into the battery.
Power through low-generation periods
When solar production drops – such as at night, during poor weather, or during grid outages – the battery discharges stored energy back into the system. This energy can then be used to power essential loads, reduce grid consumption, support business continuity, or stabilise larger energy networks.
Manage peak energy demand
In commercial and industrial environments, the battery system can also support peak shaving. Peak shaving helps reduce the impact of high-demand periods by drawing stored energy from the battery instead of relying fully on the grid during expensive or constrained times. This can help businesses manage demand charges, reduce energy volatility and maintain smoother operations.
Stabilise utility-scale power systems
In utility-scale applications, battery storage plays an additional role. It can help stabilise the grid, smooth renewable energy output and support large operations where solar generation, conventional generation and grid infrastructure need to work together.

The WEG solar advantage
The benefits of WEG Africa solar battery systems
A solar battery system helps bridge the gap between available solar resource and real-world energy demand. WEG Africa’s solar battery systems form part of a complete ecosystem – solar modules, inverters, batteries, monitoring and engineering support – designed to work together with reliability, safety and long-term efficiency in mind.
Backup during grid outages
A solar battery system stores energy for use during outages, helping homes and businesses keep critical loads running when the grid is unavailable.
Nighttime solar use
Battery storage allows daytime solar energy to be used at night, helping users get more value from their solar system and rely less on the grid.
Peak shaving
Peak shaving allows commercial and industrial users to draw on stored battery power during high-demand periods, reducing reliance on the grid.

Grid stabilisation
In larger applications, solar battery systems can help stabilise the grid by managing energy flow, storing excess generation and supporting controlled discharge.
Flexible expansion
WEG Africa’s modular battery systems can scale with growing energy needs, allowing users to start with current demand and expand over time.
Long-term value
A solar battery system is not only about backup. It supports energy strategy, operating cost control, sustainability goals, infrastructure resilience and long-term business continuity.
Solutions
Solar battery system applications across Africa
WEG Africa solar battery systems are designed for multiple applications, from homes to large-scale energy projects.
Residential
For homeowners, farms, villas and remote residences, a solar battery system provides a practical way to store solar energy for nighttime use and backup during grid interruptions. The SBW CB100 is particularly suited to this segment. Its 10 kWh modular design allows homeowners to start with a practical storage size and expand if their energy needs grow.
Commercial & industrial
For businesses, energy interruptions are not just inconvenient – they affect productivity, revenue, safety, customer service and operational planning. A commercial or industrial solar battery system can support peak shaving, backup power, self-consumption and operational continuity. This is relevant for shopping centres, residential estates, hotels, schools, factories, agricultural operations, telecoms infrastructure and other business environments.
Utility-scale
For utility-scale projects, a solar battery system becomes part of the wider energy infrastructure. It supports energy storage, grid stabilisation, hybrid power integration and large-scale project resilience. WEG Africa supplies PCS and battery systems tailored for utility-scale applications, with flexible warranties depending on project requirements.
Smart monitoring
Solar battery system & WEG PV Cloud
A solar battery system performs best when users can see what is happening in real time. WEG PV Cloud supports monitoring of solar generation, energy consumption, battery status and system performance through web and mobile access.
This gives homeowners, businesses, installers and service teams better visibility over how energy is being produced, stored and used.
WEG PV Cloud can help users track energy generation, monitor battery status, view consumption patterns, monitor system health, access performance information remotely, support maintenance checks and understand savings over time.
For larger systems, monitoring becomes even more important. It helps facilities teams, engineers and project owners identify issues, track system performance and manage energy assets more effectively.


How to choose
choose the right solar battery system
Choosing the right solar battery system starts with understanding how energy is used, when power is needed, and what level of backup or cost control is required.
A residential user may need a system that covers essential loads during outages and stores daytime solar energy for evening use. A business may need peak shaving, operational backup and a scalable system that can grow with the facility. A utility-scale project may need a tailored PCS and battery solution that supports grid stability and large-scale energy management.
